Buttons and Studs, of which UNITED STATES PATENT OFFICE.

SILAS J. ALLEN, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO JAMES B. RICHARDSON, OF SAME PLACE.

DETACHABLE BUTTON OR STUD.

SPECIFICATION forming part of Letters Patent No. 289,370, dated December 4, 1883,

' Application filed August 31, 1883. (N model.)

To caZZ whom it may concern:

Be it known that I, SILAS J. ALLEN, a citizen of the United States, and a resident of the city and county of Providence, in the State of Rhode Island, have invented a new and useful Improvement in Detachable Sleeve and Collarthe following is a specification.

My invention relates to sleeve and collarbuttons and studs in which there is a curved post slotted and hinged to operate in conjunction with an oppositely-curved solid 1308i fixedly attached to the-back plate of the button, so that the slotted post will play across the fixed post to form interlocking arms to secure the button in the garment.

The objects of my invention are to provide a button cheap in construction, not,liable to get out of order, and one which can be easily for the journals to a.

inserted in and removed from the garment, and at the same time be free from liability to detach itself. These ends are attained by the special construction illustrated in the accompanying drawings, in which Figure l is a side or edge view, showing by the dotted lines the slotted lever thrown into position to secure the button in the garment. Fig. 2 is a Vertical central section. Fig. 3 is the back plate. Fig. 4. is the slotted post. Fig. 5 shows the solid fixed post, the back plate, and lining of the button.

A is the curved post, slotted, as shown in Figs. 2 and 4, to receive the oppositely-curved solid post B. This post A is provided with a rectangular enlargement to form a foot, a, which is rounded at its extremities to form journals a a. The back plate, 0, is struck out with the irregular-shaped slot and raised lugs e e-the former to receive the foot of the post, and the latter to form a socket or journal-box The curved fixed post B is soldered or otherwise attached to the back plate, as shown in Fig. 5. Between the back plate, O, and the lining m, I place a flat steel spring, a:, common to all but-tons of this class, which regulates and controls the movement of the post A. The rim 0' can of course be made of any desired shape.

In practical construction the setting 8 is placed in the rim 1, the lining m upon it, the spring a: next, then the post A being passed through the back plate, 0, from the under side until the journals ao engage the lugs e 6, when they are placed over the other parts and the edge of the rim turned down upon the back plate in the usual manner, and the button is completed, and the post B passes through the slot in the post A.

In practical operation, the two posts being in their normal positions, as shown in Fig. 1, their ends are inserted in the button-hole, and then the post A, made to' assume the dottedline position shown in Fig. 1, will force the button into place in the garment, and retain the button in place firmlyand reliably. To detach the button, pressure must be.used on the post A until it assumes the normal position indicated in Fig. l by the full lines. In swaging up the back plate a lip is left at one side of the slot immediately in front of the fixed post to form a stop for the slotted post when it is thrown over to lock the button. To make a firmer stop, I prefer to slot the post only as shown, so that that portion left between the slot and the foot of the post may act as a stop; but my invention will be equally opera I tive and practical if the post is slotted clear to the foot a, as the raised portion of the back plate will then form the stop.

I claim as my invention and desire to secure by Letters Patent In a button or stud, the curved slottedpost A, provided with a rectangular foot, a, and journals (1 a, combined with a spring, 00, a back plate, 0, provided with a slot and lugs,

e e, and a curved post, B, fixedly secured to the back plate, and adapted to enter the slot in the post A and interlock with said post A to fasten the button in the garment.

SILAS J. ALLEN.
